CSTLS4M91G53-B0

Resonators Overview

The CSTLS4M91G53-B0 is a piezoelectric ceramic resonator from Murata Electronics, designed for microcomputer time base oscillators. It operates at a nominal frequency of 4.91 MHz with a tolerance of ±0.5% and frequency stability of ±0.2%. The component features a built-in capacitor of 15 pF and a maximum resonant impedance of 30 Ohms. It utilizes a three-pin through-hole mounting configuration. The device supports an operating temperature range from -20°C to +80°C.

Resonators Feature Summary

• Integrates a built-in capacitor to simplify circuit design
• Provides stable frequency generation for microcontroller time bases
• Utilizes a three-pin through-hole package for reliable mounting

Resonators Applications

• Microcomputer time base oscillator circuits
• Embedded system clock generation
• General-purpose timing applications requiring stable frequency reference

Resonators Procurement Notes

Verify the specific suffix B0 against official Murata documentation to confirm the through-hole variant and pin configuration. Ensure the required load capacitance matches the integrated 15 pF specification. Cross-reference the operating temperature range with application requirements before procurement.

Resonators Selection Notes

Select this component when a through-hole ceramic resonator with integrated capacitance is required for microcontroller applications. Compare the 30 Ohm impedance limit against circuit drive levels. Verify that the 4.91 MHz frequency aligns with system timing needs and that the ±0.2% stability meets precision requirements.

Resonators Part Context

This part belongs to the CERALOCK family of piezoelectric ceramic resonators. It serves as a cost-effective alternative to quartz crystals in applications where moderate frequency stability is sufficient. The through-hole format distinguishes it from surface-mount variants within the same product line.

Resonators Replacement Considerations

Direct substitutes include other Murata CERALOCK series resonators with matching 4.91 MHz frequency and through-hole packaging. Verify equivalent impedance and capacitance values when considering cross-manufacturer alternatives.
