ECS-45K20A

Overview

The ECS-45K20A is a monolithic crystal filter manufactured by ECS Inc., designed for through-hole mounting in the UM-1 package. It operates at a center frequency of 45 MHz with a bandwidth of 20 kHz and an impedance of 910 Ohms. The component features two poles and offers insertion loss characteristics typical of its series. It supports an operating temperature range from -20°C to +70°C, ensuring reliability in standard industrial environments.

Feature Summary

• Monolithic construction provides stable filtering performance at 45 MHz
• Two-pole design ensures effective signal selection within the 20 kHz bandwidth
• Through-hole UM-1 package facilitates reliable PCB integration

Applications

• Intermediate frequency (IF) stages in radio receivers
• Communication equipment requiring precise 45 MHz filtering
• Industrial control systems utilizing crystal filter technology

Procurement Notes

Verify the specific datasheet version for exact electrical tolerances and mechanical dimensions before finalizing designs. Confirm that the UM-1 footprint matches your PCB layout requirements. Ensure the operating temperature range aligns with your application environment. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a fixed 45 MHz center frequency with narrow 20 kHz bandwidth is required. The two-pole configuration suits applications needing moderate selectivity. Consider the through-hole mounting type if surface-mount alternatives are unsuitable. Verify compatibility with surrounding circuit impedance levels.

Part Context

This part belongs to the MCF series of monolithic crystal filters from ECS Inc. These components are engineered for cost-effective, high-performance filtering solutions. The series is widely used in consumer electronics and industrial communications where stable frequency response is critical.

Replacement Considerations

Check for direct substitutes within the ECS MCF series that match the 45 MHz frequency and 20 kHz bandwidth. Verify pinout compatibility and mechanical dimensions for any alternative UM-1 package components.
