QPL MIL-PRF-21038/27
Pico’s 682xx series of pulse transformers are designed to meet QPL MIL–PRF-21038/27 standards. These units are in strict compliance to MIL–PRF–21038. Pico is the supplier for MIL–PRF-21038/27 -01 thru -31 parts. The 682xx series have high input impedance from 75 kHz to 1 MHz over the temperature range of from -55C to +130C. These transformers have maximum 20% droop and over shoot is 1V maximum. The common mode rejection (CMR) is greater than 45dB. These units are designed to withstand 100Vrms from primary to secondary and are epoxy encapsulated and achieve MSL of 3. As always, Pico offers smallest possible packaging with high reliability. We are a QPL facility that are able to test these transformers to level M and level T of MIL-PRF-27.
