Special Features

  • Specs & Cross-Refs — Center frequency 450 kHz (450 ± 1.5 kHz); 6 dB bandwidth ±7.5 kHz (15 kHz total); 5-pin 4+1 layout; through-hole DIP body approx. 11.0 × 7.0 × 8.0 mm; low-loss ladder filter topology for IF sections. Cross-reference numbers: LT450EW, LT450E, CF 450EW, CFWS450E (verify frequency and pin layout before purchase)
  • Installation & Position — Mounts on the radio's 450 kHz IF stage PCB footprint; match the single “key” pin of the 4+1 layout to the board marking; observe lead spacing; use low-heat, ESD-safe soldering and clean flux residues to minimize leakage. Compatible with 4+1-pin 450 kHz IF filter footprints commonly found in communications equipment; always confirm orientation in the service manual before power-up
  • Applications & Compatibility — Designed for communications receivers and transceivers; commonly used where 15 kHz (±7.5 kHz) wide IF is specified (e.g., FM(W) / wider-band paths). Compatible with 450 kHz IF stages in commercial and amateur radio gear, scanners, and similar equipment (check schematic for 450 kHz callouts).
  • What Problems It Addresses — Replacing a worn 450 kHz IF filter can restore selectivity, reduce adjacent-channel bleed/crosstalk, and improve intelligibility in sets that have degraded filters. After a high-class filter replacement, radios can receive more desired signal at the same noise level and exhibit cleaner channel separation (results vary by radio/design).
  • Complementary/Alternative Parts — If your set specifies other bandwidths/frequencies, select from the same family: LT450FW/GW/HW for narrower 450 kHz options, or LT455EW/CF 455EW if the design uses 455 kHz instead. Always match center frequency, bandwidth, and pin layout (3+2 vs 4+1) to the board footprint and service manual

Description

LT450EW 450 kHz IF Ceramic Filter (4+1 pins)
Function: 5-element ceramic ladder filter for 450 kHz intermediate-frequency stages in communications receivers and transceivers.
Electrical: Center freq. 450 ±1.5 kHz; 6 dB bandwidth ±7.5 kHz (15 kHz total); wide-band “E” grade for FM(W)/wide IF paths.
Package: Through-hole DIP, 5 pins in a 4+1 keyed layout; body approx. 11.0 × 7.0 × 8.0 mm.
Typical Use: IF filtering to improve selectivity and adjacent-channel rejection when refurbishing or repairing radio equipment.
Cross-Reference (for search/use verification): LT450EW, LT450E, CF 450EW, CFWS450E. Always match frequency, bandwidth, and pin layout to your PCB footprint.
Install Notes: Desolder the original filter with ESD-safe technique; align the single key pin; solder cleanly and remove flux; verify the IF alignment per service manual.
In the Box: 1 × LT450EW 450 kHz ceramic IF filter (4+1 pins).
Compatibility reminder: This component fits equipment that specifies a 450 kHz IF filter with a 4+1 pin footprint. It is not an automotive relay or vehicle-specific part.
