HIGH FREQUENCY MAGNETICS

Specialty Surface Mount ShieldedTransformer

TM00107

•

Operating temperature range: -40° C to +85° C

Meets IEC 695, 2-2 flammability requirements

•

Operates as a high frequency pulse transformer or

as a high frequency analog transformer in various

telecom circuits requiring very high voltage step-up

ratio

PWB Process Capability: standard printed wiring board

assembly techniques, total-immersion cleaning

•

Interwinding Electrostatic Shield provides low

capacitance and high EMI suppression

•

Reliability testing: Shock, vibration, temperature cycling,

temperature - humidity - bias

Electrical equivalents: 2664F, 2741P2, 2779A
