✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Precision Timing Circuits: The C0G/NP0 dielectric ensures minimal capacitance change over temperature (−55°C to +125°C), making it ideal for oscillator and PLL loop filters where ±5% tolerance matters.
• High-Frequency RF Decoupling: With 0.12µF at 25V, this MLCC offers low equivalent series resistance (ESR) and excellent frequency stability, critical for noise suppression in RF power amplifiers and transceivers.
• Automotive Infotainment Modules: Murata’s reliability and the 1206 package allow robust solder joint inspection while the 25V rating provides margin for 12V / 5V rail filtering in harsh environments.

Key Features & Advantages

• C0G/NP0 Dielectric: Near-zero temperature coefficient (±30 ppm/°C) ensures stable capacitance across operating temperature, outperforming X7R in resonant circuits.
• 1206 Footprint: Balanced size for both prototyping and automated assembly, offering higher capacitance density than 0805 while remaining manageable for manual rework.
• ±5% Tolerance: Tight capacitance control reduces design margin requirements, enabling more accurate filters and timing delays without additional tuning.

Frequently Asked Questions

1. Q: What makes GRT31C5C1E124JA02L different from a standard X7R MLCC?
   A: Unlike ferroelectric X7R, the C0G/NP0 dielectric has no voltage coefficient and minimal aging, making this part the best choice for frequency-dependent circuits that demand stable 0.12µF ±5% over temperature.
2. Q: Is GRT31C5C1E124JA02L RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply. Small quantities for testing are always available.
