Products and key models CSTLS4M00G53 B0 — 4 MHz ceramic resonator (clock/timing element). CSTLS6M00G53 R0 — 6 MHz ceramic resonator. CSTLS8M00G53 B0 — 8 MHz ceramic resonator. CSTLS16M0X53 B0 — 16 MHz ceramic resonator. Inventory note: 50 pieces of CSTLS 8 MHz quartz crystal oscillator available. Why customers need these parts Provide a stable, discrete frequency source for digital and analog circuits where a fixed clock or timing reference is required. Simplify circuit design by supplying a ready-made resonator/oscillator matched to common microcontroller and timing needs. Allow quick repairs, prototyping, and production runs with off-the-shelf standard frequencies. What makes these parts stand out Clear, standard frequencies (4 MHz, 6 MHz, 8 MHz, 16 MHz) that match widely used microcontrollers and timing requirements. Available both as ceramic resonators (models listed above) and in quantity as a quartz crystal oscillator variant (50 pieces of the 8 MHz CSTLS part) to suit different precision and sourcing preferences. Branded CSTLS models for consistent identification and replacement compatibility. Function and compatibility Function: act as a frequency-determining element for clock generation and timing circuits. Typical compatibility: microcontrollers, microprocessors, timers, communication interfaces, and other embedded systems that accept an external resonator or crystal clock input. Interchangeability: model-specific frequencies align with common design requirements; verify device input requirements (resonator or crystal) when replacing parts. Material and construction Ceramic resonator models indicated above are ceramic-based frequency devices. The available stock of CSTLS 8 MHz is a quartz crystal oscillator (50 pieces), noted separately for users who require quartz construction. Performance and practical attributes Operate at the specified nominal frequencies (4 MHz, 6 MHz, 8 MHz, 16 MHz). Purpose-built for clock/timing roles in electronic circuits. Model codes (for example CSTLS8M00G53 B0) allow precise identification when ordering or replacing parts. Use scenarios Embedded development: Provide a reliable 8 MHz clock source for an 8-bit microcontroller running firmware where the board design calls for an external resonator. Repair and maintenance: Replace a failed ceramic resonator in consumer electronics or home appliance control boards with the matching CSTLS model to restore timing functionality. Small-volume production or prototyping: Use the 16 MHz CSTLS16M0X53 B0 for projects requiring higher clock speed or the 6 MHz CSTLS6M00G53 R0 for legacy systems; leverage the 50-piece lot of 8 MHz quartz oscillators when a batch of precise quartz devices is needed. Ordering and selection tips Match the exact CSTLS model number and frequency to your circuit requirements to ensure compatibility. Choose the ceramic resonator models for standard clock needs; choose the stocked 8 MHz quartz oscillator pieces if your design requires quartz construction. Confirm the host device’s expected input (resonator vs. crystal/oscillator) before installation. Contact or procurement consideration When ordering, reference the full model designation (including suffixes such as B0 or R0) to avoid mis-matches.
