- 1200 ohm CT primary, 600 ohm CT secondary
- Useful impedance range 600/300 to 2400/1200 ohms
- DC resistance 80 ohms primary, 53 ohms secondary
- 300 Hz to 100 kHz +/- 0.5 dB at 100 mW
- Windings interchangeable for step-up or step-down use
- Potted, completely sealed, 0.1 oz, pin-type PCB mount
The 101H is a miniature potted audio transformer for P.C. board mounting that steps a 1200 ohm center-tapped primary down to a 600 ohm center-tapped secondary. It is a practical choice for designers matching a higher-impedance audio stage to a 600 ohm line in a compact, board-level part.
The pin-type package uses rugged potted construction to produce a completely sealed unit that withstands severe environmental conditions. Net weight is only 0.1 oz. Either winding may be used as the primary, so the 101H can also step 600 ohms up to 1200 ohms.
Nominal DC resistance is 80 ohms on the primary and 53 ohms on the secondary. The useful impedance range extends from 600/300 to 2400/1200 ohms primary/secondary, so the same part covers a range of source and load pairs at the same 2:1 impedance ratio.
Series performance data for the 101H:
- Minimum frequency range 300 Hz to 100 kHz +/- 0.5 dB at 100 mW
- 200 Hz to 100 kHz +/- 0.5 dB at +10 dBm and at +15 dBm
- 300 Hz to 100 kHz +/- 0.5 dB at +20 dBm
- All frequency measurements taken with no DC current saturation
This part is RoHS and REACH compliant and ships at 0.01 lbs.
Ideal For
- Matching 1200 ohm audio stages to 600 ohm lines
- Board-level balanced audio coupling
- Compact sealed audio interfaces
