Chip resistors are 100% lead free without exemption
Stackpole's RNCP series chip resistors utilise high volume thin film technology to provide cost effective chip resistors that are 100% lead free and RoHS compliant without exemption. The RNCP's thin film technology doesn’t require the lead containing dielectric as do most commercial high volume thick film chip resistors.
Surface mount resistors offer higher working voltages
The HVC series from Stackpole is a thick film surface mount chip resistor series designed for high voltage handling and high resistance value. The working voltages for several chip sizes have now been improved: the 1206 size now is rated at 1500V, the 2010 is now 2000V and the 2512 is now 3000V.
Metal film melf resistors offer high power ratings of 0.4W
Stackpole announces the release of the MLFA Series of AEC-Q200 qualified precision metal film melf resistors. AEC-Q200 has become an important passive component qualification standard for a variety of industries and end products and is no longer merely an automotive requirement.
SMD current sense device offers resistances to 5mΩ
Stackpole Electronics has announced that its CSRF series of SMD current sense resistors is now available in resistances down to 5mΩ in an 0402 chip size. This low resistance value, combined with the small package size, enables efficiency improvements in small portable electronic devices and potential downsizing of existing designs.
SMD shunt resistors now available in 0.2mΩ versions
Stackpole has revealed that its HCS high current SMD shunt resistors are now available in a 0.2mΩ resistance value in chip sizes of 3920 and 5930. The HCS has an all metal welded construction with a raised resistance element which provides more efficient thermal conduction, allowing the HCS to handle higher currents with lower self-heating compared to comparable flat chips.
3W current sense chip is now AEC-Q200 qualified
Stackpole Electronics has announced that its CSSH2512 3W current sense chip has now been qualified to AEC-Q200. The CSSH2512 offers resistance values from 0.5 up to 10mΩ in tolerances as tight as 0.5% and TCR as low as 25ppm.
Resistors offer lower PCB temperatures
Stackpole's BR series is a radial leaded thru hole current sense resistor series offering power ratings up to 5W. The BR series elevates the resistive element off of the board for maximum cooling into the ambient air and minimising the amount of heat that must be dealt with at the board level.
Resistors are AEC-Q200 qualified for 1% tolerances
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.
SMD shunts sizes add 0.2mΩ resistance value
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.
Precision chip resistors are sulfur & moisture resistant
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...
