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

Typical Applications & Why This Part Fits

• High-Frequency Resonant Circuits: The C0G/NP0 dielectric and 0.039UF value deliver ultra-low ESR and negligible capacitance drift, making this MLCC ideal for oscillator and filter designs requiring precise tuning at 50V bias.
• Timing and Coupling Stages: With ±5% tolerance and a 50V rating, the GRM31M5C1H393JA01L ensures reliable AC coupling and timing in industrial control modules where 0.039UF stability is critical.
• Automotive Sensor Signal Conditioning: The 1206±5% footprint combined with C0G/NP0’s flat temperature coefficient supports consistent signal integrity in harsh environments, while the 50V rating provides headroom for supply transients.

Key Features & Advantages

• C0G/NP0 Dielectric: Offers ±30ppm/°C temperature stability, ensuring capacitance remains 0.039UF across -55°C to +125°C without voltage-induced derating.
• 50V Rated Voltage: Provides robust margin for 12V/24V/48V rails, reducing failure risk in power conditioning and decoupling applications.
• 1206 SMD Package: Large termination pads enable strong solder joint reliability, suitable for both manual prototyping and automated reflow assembly.

Frequently Asked Questions

1. Q: What makes GRM31M5C1H393JA01L different from a standard X7R MLCC?
   A: Unlike X7R, this part uses C0G/NP0 dielectric, which guarantees no DC bias loss and extremely low capacitance change over temperature, vital for 0.039UF precision circuits.
2. Q: Is GRM31M5C1H393JA01L RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting current environmental directives.
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 for this 0.039UF 50V C0G/NP0 MLCC.
