Low Profile Line Matching Transformers are Ideal for Modems, Laptops, Fax Machines etc

The Model LM302-1L is compatible with all major standard modem circuitry that meets V.32, V.32 bis and V.34 industry requirements. It is suitable for a wide range of voice and data applications telecom equipment, instrumentation, portable devices, office equipment, security systems etc.

The LM302-1L provides space-efficient isolation between sensitive electronics and telephone lines. With a dielectric strength tested to 6500 VDC, it meets various international safety standards including UL60950 and BABT. This device’s high dielectric strength safeguards equipment users by protecting them from electrical shock.

Developed for high performance, the LM302-1L is a symmetrical design meaning that there is no real primary or secondary winding. Key circuit specifications include: impedance at 600 ohms (both primary/secondary), turns ratio is 1:1 and insertion loss at 2Khz is 1.5 db max
A though-hole device, the LM302-1L comes in a 0.706 (17.9 mm) square package. It features a seated height on only 0.422 inches (10.7 mm), which makes it useful in many high density designs.

With its vacuum encapsulated package, the sealed LM302-1L withstands high temperature soldering and operating temperature environments from –20ºC to +85ºC and a storage range of -40ºC to +85ºC. It is available in tape-and-reel or tube packaging for auto insertion equipment.
