FAQ

Under normal operating conditions, the estimated service life of a chip resistor is approximately 10 years. However, factors such as excessive ambient temperatures or chemical corrosion can shorten this lifespan; in extreme cases, the service life might be reduced to five or six years, or even lead to immediate component failure—though typically, the lifespan is reduced by two to three years. Actual service life is influenced by various factors, so this estimate is for reference only.

The color of the ceramic element in Murata chip capacitors is determined by the ceramic material used; common colors include brown and gray. However, the perceived color may vary depending on lighting conditions (such as the light source or light intensity).

• For chip capacitors larger than size 1210, a significant temperature difference develops between the component’s surface and its interior; this thermal gradient can cause the component to crack, making wave soldering unsuitable.
• For chip capacitors smaller than size 0402, wave soldering may cause the components to detach or result in solder bridging; therefore, the wave soldering process is also unsuitable for these sizes.

There is no need to worry about cracking due to exposure to low temperatures. Since the dielectric material is ceramic, please avoid thermal shock or thermal shock cycling caused by rapid temperature changes.

As the dielectric material is ceramic, please avoid thermal shock or thermal shock cycling caused by rapid temperature changes.

The color of the ceramic element in Murata chip capacitors depends on the ceramic material itself; common colors include brown and gray. However, the actual perceived color may vary depending on lighting conditions (such as the light source or light intensity).

Connecting them in series for fail-safe purposes is a viable approach. However, please ensure that the circuit voltage complies with the specifications of each Murata chip capacitor. Be sure to verify that the rated voltage of each capacitor in the series connection exceeds the circuit voltage.
