What is ERJT08J91RV used for?
The ERJT08J91RV 91Ω resistor is used in transmission line impedance matching for USB, Ethernet, and LVDS differential pair circuits where 91Ω termination reduces signal reflections at cable or PCB trace endpoints. It serves as a current limiting resistor for RS-232 and CAN bus transceiver input protection, where voltages up to 36V may be applied and 0.33W dissipation provides adequate headroom. The 91Ω value also finds use in base-emitter resistor networks for transistor biasing and emitter degeneration in amplifier stages requiring modest gain and input impedance control.

Frequently Asked Questions
How does ERJT08J91RV serve as a transmission line termination resistor in differential signal designs?
A 91Ω resistor is commonly used as a single-resistor AC termination across differential pairs in USB full-speed and RS-485 differential buses where 100Ω to 120Ω characteristic impedance requires close matching. Placing the ERJT08J91RV at the receiver end reduces signal reflections at data rates from 1 Mbps up to 480 Mbps, improving eye diagram quality and reducing bit error rates in high-speed digital designs.
What current limit does ERJT08J91RV provide for protecting a 5V RS-232 or GPIO input from overvoltage?
In an input protection network with a 91Ω series resistor and ESD clamp diodes, a 12V RS-232 line voltage would drive a clamped current of approximately (12V - 5.7V) / 91Ω = 69mA through the resistor, dissipating about 0.43W in worst-case transient conditions. For continuous 12V RS-232 input, a 91Ω value limits steady-state current to manageable levels while the 0.33W rated device handles brief transient bursts without damage.
What RC low-pass filter cutoff frequency does ERJT08J91RV create with a 100pF capacitor?
A first-order RC low-pass filter using 91Ω and 100pF has a -3dB cutoff frequency of f = 1 / (2π × 91 × 100×10⁻¹²) ≈ 17.5 MHz. This frequency range is suitable for filtering high-frequency noise on analog signal lines above 17MHz while passing audio and lower intermediate frequency signals, making it useful in RF front-end filtering and EMI suppression on ADC input paths.
Why might a designer choose 91Ω rather than a standard 100Ω resistor for an impedance-matching application?
The E96 standard resistor series includes 91Ω as a preferred value that sits between the E24 values of 82Ω and 100Ω, offering finer impedance matching accuracy for 90Ω to 93Ω characteristic impedance lines found in some coaxial and PCB stripline designs. Using 91Ω instead of 100Ω reduces reflection coefficient by roughly 5% in a 91Ω-terminated 91Ω line versus a 100Ω resistor in the same system, a meaningful improvement in GHz-range RF board designs.
