Specifications subject to change without notice. Document 153 Revised 11/26/02

Coilcraft’s EMI filter modules are an easy, effective way

to eliminate the problems of stray electromagnetic inter-

ference (EMI) in signal cables running between poorly

filtered equipment.

Available in DB-25, -15 and -9 versions, the modules

plug between an RS-232 cable and an input or output

port. Common mode magnetics filter all lines including

the frame ground, attenuating EMI over the critical

30 - 300 MHz range while leaving data signals totally

undisturbed.

Comparable EMI filters for circuit board mounting are also

available.

Typical Attenuation

1. Measured on HP 8753D network analyzer. Ref: 50 Ohms.

2. Operating temperature range –40°C to +85°C.

3. Electrical specifications at 25°C.
