CSBLA640KEC8-B0

Resonators Overview

The CSBLA640KEC8-B0 is a ceramic resonator from Murata Electronics' CERALOCK series, designed for through-hole mounting. It operates at a nominal frequency of 640 kHz with a stability tolerance of ±0.3% and an equivalent series resistance of 40 Ohms. The component functions within a temperature range of -20°C to +80°C. This specific part number is currently classified as obsolete or end-of-life, indicating that production has ceased and availability is limited to existing stock.

Resonators Feature Summary

• Utilizes CERALOCK technology for stable frequency generation in compact packages
• Designed for direct integration into through-hole circuit boards
• Provides inherent impedance matching characteristics via integrated resistor

Resonators Applications

• Microcontroller clock sources requiring low-cost timing solutions
• Simple digital logic circuits needing stable oscillation frequencies
• Consumer electronics with basic timing requirements

Resonators Procurement Notes

This component is officially listed as obsolete by the manufacturer. Procurement must rely on remaining distributor inventory or secondary market suppliers. Verify lot dates and storage conditions carefully due to potential long-term warehousing. No new production units are available directly from Murata Electronics.

Resonators Selection Notes

Engineers should evaluate alternative active crystals or newer passive resonator families for new designs. If replacement is necessary for existing hardware, ensure pin compatibility and electrical parameters match the original design constraints. Consider thermal stability requirements when selecting substitutes for this wide-temperature-range component.

Resonators Part Context

Part of the CSB series CERALOCK line, which integrates ceramic resonators with internal resistors. This series targets cost-sensitive applications where moderate frequency stability suffices. The CSBLA640KEC8-B0 represents a specific frequency variant within this broader family of through-hole components.

Resonators Replacement Considerations

No official public substitute part numbers are documented for this obsolete item. Engineers must identify third-party equivalents based on identical frequency (640 kHz), package type, and resistance values.
