CSBLA400KECE-B0

Resonators Overview

The CSBLA400KECE-B0 is a ceramic resonator from Murata Electronics' CERALOCK series, designed for through-hole mounting. It operates at a nominal frequency of 400 kHz with a frequency stability of ±0.3%. The component features an impedance of 20 Ohms and functions within a temperature range of -20°C to +80°C. Its physical dimensions are 7.9 mm in length, 3.6 mm in width, and 9.3 mm in height.

Resonators Feature Summary

• Integrates piezoelectric ceramic elements with internal resistive components to simplify circuit design by eliminating external discrete parts.
• Provides stable frequency generation suitable for microcontroller clock sources and timing applications.
• Utilizes a robust through-hole package construction for reliable mechanical attachment on printed circuit boards.

Resonators Applications

• Microcontroller system clock generation
• Timing circuits for embedded systems
• Low-cost oscillator replacements

Resonators Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct tolerance and packaging specifications. Confirm that the through-hole footprint matches the target PCB layout dimensions. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the requirements of the intended application environment.

Resonators Selection Notes

Select this component when a cost-effective, low-frequency clock source is required for through-hole designs. Consider the 400 kHz frequency and ±0.3% stability as primary constraints. Evaluate the 20 Ohm impedance against the driving capability of the host oscillator circuit. Compare physical size constraints against available board space.

Resonators Part Context

This part belongs to the CSB series of ceramic resonators, which are widely used in consumer electronics and industrial controls. It serves as a passive timing element, distinct from active quartz crystals or oscillators. The CERALOCK branding indicates integrated resistance capabilities within the ceramic body.

Resonators Replacement Considerations
