Stackpole's RPC Series of anti-surge chip resistors is now AEC-Q200 qualified for 1% tolerances and wider. Along with providing top notch pulse handling, the AEC qualification provides additional assurance to designers that the RPC Series is able to pass the stringent electrical and environmental requirements set forth by the AEC standard.

The HCS series from Stackpole now includes an 0.2mΩ resistance value in the 3920 and 5930 chip sizes. This extremely low resistance value allows higher power current sensing with greater efficiency. In addition, the all-metal raised element means lower PCB temperatures due to increased convection under the part. The HCS typically runs 15 to 30°C cooler than comparable sized flat chips.

Resistant to the effects of both sulfur and moisture, a series of thin film precision chip resistors have been unveiled by Stackpole Electronics. While thin film nichrome resistors typically have difficulty withstanding high humidity environments under low power, Stackpole's proprietary materials and processing protects the nichrome element and performs as well under high humidity testing as much more expensive technologies such as tantalum nitri...

Stackpole has expanded its HCS series high current shunt chip resistors to include a 1206 size part rated at 2W. The HCS series combines an elevated resistive element to lower the induced heat on the PCB with low resistance values down to 0.3mΩ to achieve this outstanding performance.

The popular RNCF series from Stackpole is a thin film chip resistor series capable of outstanding precision. From sizes 0402 up to 2512 the RNCF offers 0.01% tolerances for a wide range of resistance values. The RNCF also offers TCR down to 5ppm for a significant value range for the same sizes.

Based on foil on ceramic carrier technology, the CSRF series from Stackpole offers very low resistance values and low TCR in small chip sizes. Utilising proprietary materials and manufacturing processes, Stackpole now offers a higher power rating version. Both with TCR from 75 to 200 ppm and resistance values down to 5mΩ, the CSRF0402-HP has a power rating of 0.25W and the CSRF0603-HP has a power rating of 0.5W.

  Stackpole has expanded its CSS series of current sense chip resistors to include a 0.33W rated 0603 size and a 0.5W rated 0805 size. Both offer resistance values of 5, 10, and 15mΩ in 1% tolerances and 50ppm TCR.

  Utilising high voltage power film to achieve high working voltages and high overload voltages, the ASR/ASRM series of anti-surge resistors has been released by Stackpole. The devices withstand repeated high voltage pulses of up to 10KV every 5 seconds with very little resistance shift.

  Stackpole Electronics announces the release of the RAVS series of convex termination anti-sulfur chip resistor arrays. The RAVS series utilises thick film technology with lower silver inner terminations to significantly reduce the susceptibility of the array to contamination by sulfur.

Stackpole Electronics announces its tolerance expansion for the RGC series. The thick film technology is now available in ±0.1% tolerances in chip sizes from 0603 through 2512. This development is a significant enhancement to the series that allows engineers to take advantage of precision tolerances while avoiding design challenges associated with thin film resistors, namely high moisture/humidity.

  Stackpole Electronics, has released the HCC8420 high current chassis mount shunt resistors. The HCC8420 is rated at 15W and has a resistance value of 0.1mΩ and can handle currents up to 350A. The TCR for this part is an impressive 100ppm/°C.

  A series of foil on ceramic current sense chip resistors that offers resistance values among the lowest in 0402 and 0603 chip sizes has been released by Stackpole Electronics. The CSRF series consists of the CSRF0402–HP and the CSRF0603.

Stackpole’s EWT Series of vitreous enamel coated tubular wirewounds are a good choice for high power load dump applications. The EWT Series is available in power ratings from 12 watts up to 1300 watts and the vitreous enamel coating withstands temperatures of up to 500C.

The RAF Series from Stackpole is a small size chip resistor array consisting of two or four isolated 0201 equivalent resistors in a single rectangular shaped chip with no scallops or holes. By removing the scallops that chip arrays usually have, the substrate becomes less complex and less expensive.

The ZOV Series of metal oxide varistors is a series of epoxy coated square varistors with sizes from 23mm to 60mm. These high energy varistors come in a single disc, double, triple and quadruple disc versions with pulse current capabilities of up to 80kA.

The RNCP series from Stackpole has no silver or other susceptible metals in the terminations to cause sulfur contamination. In addition, the thin film resistive element provides outstanding stability and higher power ratings compared to commodity thick film chip resistors.

Stackpole’s RC series is an axial leaded carbon composition technology available in 1/4W, 1/2W, and 1W power ratings. The RC’s dense carbon slug element handles high energy surges much better than metal film based surge resistors.

Stackpole announces the release of the CSRF0603 and CSRF0402 sizes to add to their broad current sense resistor product group. The CSRF0603 is available in resistance values from 5 to 10 milliohms in 1% tolerance and 75 ppm TCR.

Stackpole Electronics, Inc., through its strategic alliance with KEKO Varicon, announces the AVL Series of radial leaded automotive varistors that are designed to protect automotive level electrical systems from transient voltage events. The AVL Series is designed specifically to protect 12V, 24V, and 42V automotive electrical systems.

The BR series from Stackpole is a thru hole current sense resistor series offering power ratings up to 5 watts with low PCB temperatures. The BR series elevates the resistive element off of the board for maximum cooling into the ambient air and minimizing the amount of heat that must be dealt with at the board level.
