Notes

1. Third

harmonic

typically

exceeds

other

harmonics by 20dB.

2. Components 100% tested at 6.5 kVDC.

3. Caution: do not pass DC through windings.

Telephone line current, etc. must be diverted

using choke or semiconductor line hold circuit.

4. At signal levels greater than 100mV, Lp will

increase and Rp will decrease slightly but the

effect is usually favourable to the return loss

characteristic.

5. Excludes shipping materials. Components are

dry-packed and sealed as shipped Handle in

accordance

with

IPC/JEDEC

J-STD-033

procedure

for

components

classified

as

IPC/JEDEC J-STD-020 Moisture Sensitivity

Level 5a.
