Notes
1. Third harmonic typically exceeds other
harmonics by 20dB.
2. Components are 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.
