ECS-CTP-4.00-30-TR

Resonators Overview

The ECS-CTP-4.00-30-TR is a surface-mount ceramic resonator manufactured by ECS Inc., designed for precise frequency control in electronic circuits. It operates at a nominal frequency of 4.00 MHz with a tolerance of ±0.5% and a stability of ±0.3%. The component features built-in capacitors rated at 30 pF and an impedance of 30 Ohms, eliminating the need for external load capacitors. Housed in a compact SMD package measuring 6.00 mm x 3.00 mm with a height of 1.5 mm to 2.00 mm, it supports operation within a temperature range of -40°C to +85°C.

Resonators Feature Summary

• Integrated built-in capacitors simplify circuit design by removing the requirement for external load components.
• Compact surface-mount package facilitates automated assembly and space-constrained PCB layouts.
• Wide operating temperature range ensures reliable performance across diverse environmental conditions.

Resonators Applications

• Microcontroller clock generation
• Real-time clock circuits
• Communication interface synchronization

Resonators Procurement Notes

Verify that the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm the 30 pF internal capacitance matches the target oscillator circuit requirements. Ensure the 6.00 mm x 3.00 mm footprint aligns with the PCB layout specifications. Check RoHS compliance status if restricted substances are mandated for the application.

Resonators Selection Notes

Select this component when a stable 4 MHz reference is required without external tuning capacitors. Consider the ±0.5% tolerance for applications demanding moderate frequency accuracy. Evaluate the 30 Ohm impedance against the driving capability of the host oscillator circuit. Compare physical dimensions against available board space constraints.

Resonators Part Context

This part belongs to the ECS-CTP series of ceramic resonators from ECS Inc. The series offers various frequencies and capacitance values tailored for different timing needs. The CTP designation typically refers to standard ceramic resonator packages with integrated capacitors, distinct from XTAL or other specialized variants.

Resonators Replacement Considerations

Direct substitutes include other 4.00 MHz ceramic resonators with 30 pF built-in capacitance and similar SMD footprints. Verify equivalent impedance and tolerance specifications before substitution. Cross-reference pinout compatibility if mechanical mounting differs slightly between manufacturers.
