Quality and consistency is guaranteed through 100% testing of the specified parameters for primary inductance, leakage
inductance, turns ratio, DC resistance and interwinding capacitance.This ensures that the return loss and pulse wave shape
requirements can be fully maintained. Additionally, all parts are tested for 1500V minimum isolation.
