Overview
The LTC450GW-TR is a surface-mount ceramic filter manufactured by Transko Electronics, Inc. It operates at a center frequency of 450 kHz and features a bandwidth of 3 kHz with an impedance of 2 kOhm. The component utilizes a 4-SMD J-Lead package with dimensions of 12.00mm x 6.50mm and a maximum height of 3.30mm. It exhibits insertion losses of 6dB and is designed for AM signal processing applications.
Feature Summary
- Utilizes a 4-SMD J-Lead surface mount package for compact circuit integration
- Provides precise 3 kHz bandwidth filtering centered at 450 kHz
- Designed for low insertion loss performance in AM receiver stages
Applications
- AM radio receiver intermediate frequency filtering
- Signal processing circuits requiring 450 kHz center frequency selection
- Compact electronic devices utilizing surface mount technology
Procurement Notes
Verify the specific suffix TR indicates tape and reel packaging configuration when sourcing. Confirm the manufacturer is Transko Electronics, Inc., as distributors may list similar part numbers from other vendors. Ensure the 4-SMD J-Lead footprint matches the target PCB design constraints before procurement.
Selection Notes
Select this component for applications requiring a fixed 450 kHz center frequency with narrow 3 kHz bandwidth. The surface mount J-Lead package suits automated assembly processes. Consider the 2 kOhm impedance specification to ensure proper matching with preceding or following circuit stages in the signal chain.
Part Context
This component belongs to the family of ceramic filters produced by Transko Electronics, Inc. Similar parts include the LT450FW and LTC450BU, which share the same manufacturer but may differ in pin configuration or package style. These filters are typically used in analog communication systems requiring stable frequency discrimination.
Replacement Considerations
Direct substitutes must match the 450 kHz center frequency, 3 kHz bandwidth, and 4-SMD J-Lead package. Verify impedance compatibility with existing circuit designs. Cross-reference with Transko's current product lineup for updated revisions.
