Applications
The CRGS0603J18R anti-surge resistor is designed for circuit protection applications where transient overvoltage events or inrush currents can damage conventional resistors, such as in USB port protection, ESD-susceptible sensor interfaces, and power supply inrush limiting circuits. Its 0603 package makes it suitable for compact consumer electronics and industrial control boards where space is limited but surge robustness is required. The resistor also serves in LED current limiting, EMI filter networks, and signal conditioning circuits requiring stable 18 Ω resistance.

Frequently Asked Questions
How does the anti-surge construction of the CRGS0603J18R differ from standard thick-film resistors in terms of pulse power handling?
The CRGS0603J18R anti-surge design uses a modified thick-film resistive layer and electrode structure that can withstand short-duration pulse powers of 2 W to 5 W, significantly above its 0.25 W continuous rating, without resistive element cracking or open-circuit failure. Standard 0603 thick-film resistors rated at 0.25 W typically fail at pulse powers above 1 W to 2 W due to thermal shock in the resistive film, making the CRGS0603J18R more reliable in circuits subject to ESD events or switching transients.
For a USB 5 V bus protection circuit, how does the 18 Ω CRGS0603J18R limit inrush current during hot-plug events?
Placing the CRGS0603J18R 18 Ω resistor in series with a USB 5 V bus limits peak inrush current to approximately 277 mA at the moment of hot-plug connection when charging a 0.1 µF bypass capacitor, using the formula I = V/R = 5 V / 18 Ω. The 0.25 W steady-state rating is sufficient for 100 mA USB 2.0 low-power device loads that produce only 0.18 W dissipation across the resistor, well within the continuous rating with adequate thermal derating.
How does the ±100 ppm/°C TCR of the CRGS0603J18R affect its resistance value over an automotive operating temperature range of -40°C to 125°C?
With a temperature coefficient of ±100 ppm/°C, the CRGS0603J18R resistance changes by a maximum of 100 parts per million per degree Celsius. Over an automotive temperature range of -40°C to 125°C, representing a 165°C span, the maximum total resistance change is 1.65%, shifting the 18 Ω nominal value by at most ±0.3 Ω. This change is within the ±5% initial tolerance, so for most applications the temperature-induced drift is negligible compared to the initial tolerance.
When procuring CRGS0603J18R for a high-volume design, what lead time should engineers plan for and what is the REACH compliance status?
The CRGS0603J18R has a factory lead time of approximately 12 weeks from TE Connectivity, so engineers should place purchase orders at least 3 months before scheduled production starts to avoid supply gaps. The component is REACH compliant, meaning it does not contain substances of very high concern above 0.1% threshold, which satisfies European Union regulatory requirements for CE-marked products sold in EU markets. Stocking a buffer inventory of 4 to 8 weeks of production volume is recommended given the 12-week lead time.
