ETL > Ceramic Resonators > ETB SERIES OF CERAMIC RESONATORS
  Features:
- Superior stability of oscillating frequency in operating temperatu
- Adjustment free oscillating frequency.
- Adjustment free free-run frequency in a demodulating circuit of a stereo set.
- When using this component, combined wit a ceramic filter and a ceramic discriminator, adjustment of the sequential circuit after the IF circuit block is not necessary.

Application:
Household stereo set, car stereo set, CD cassette radio.
