Product Overview
Murata SFJ10.7MA-Z is a 10.7 MHz ceramic intermediate frequency (IF) bandpass filter designed for FM broadcast receivers and tuner amplification stages. Built with a 4-pin radial through-hole layout, it establishes the standard 10.7 MHz center frequency required for selective FM detection and demodulation.
Key Features
- Center frequency: 10.70 MHz ±30 kHz (Rank A)
- 3 dB bandwidth: 280 kHz ±50 kHz
- 50 dB bandwidth: 750 kHz maximum
- Input and output impedance: 330 ohms
- Insertion loss: 7 dB ±2 dB
- Spurious attenuation (8 to 12 MHz): 55 dB minimum
- Lead configuration: 4-pin radial through-hole with 2.5 mm - 7.5 mm - 2.5 mm spacing
- Maximum DC operating voltage: 50 VDC
Applications
- Replacing degraded or misaligned IF filters during vintage stereo tuner and FM broadcast receiver restoration
- Servicing commercial communications transceivers utilizing a 10.7 MHz intermediate frequency architecture
- Prototyping custom VHF FM receivers and software-defined radio downconverter front ends on perfboard
- Bench repairs of automotive FM head units and tabletop radios exhibiting adjacent-channel distortion
Frequently Asked Questions
What does the A marking on the back of the filter indicate?
The A marking signifies the center frequency rank, identifying this filter as calibrated to 10.70 MHz ±30 kHz.
What are the pin connections and lead spacings?
The filter has four straight leads spaced at 2.5 mm, 7.5 mm, and 2.5 mm intervals, providing balanced grounding between the input and output terminals.
Why buy an individual Murata SFJ10.7MA-Z filter here?
Finding the exact 10.7 MHz IF filter rank for an FM tuner repair usually means buying an unsorted lot or gambling on used pulls. Here you get a single, photographed, unused new old stock filter with confirmed Rank A 10.70 MHz center frequency and clean leads. Orders ship from our Idaho warehouse the same or next business day for a flat $8, and shipping is free on orders over $28.
Tuning an FM intermediate stage to dead quiet between stations comes down to an honest ceramic element. Drop this in, dial across the band, and let the tuner sing clean.
