Frequently Asked Questions
What power dissipation can the RK73B2ATTD334J handle continuously in a 330 kΩ pull-up network?
The RK73B2ATTD334J is rated for 0.25 W continuous power dissipation. In a 330 kΩ pull-up to 5 V, the maximum current is approximately 15 µA, producing only about 0.075 mW of dissipation — far below the 0.25 W limit. This leaves ample thermal headroom for elevated ambient temperatures up to 70 °C without derating.
How does the ±200 ppm/°C temperature coefficient of the RK73B2ATTD334J affect resistance drift over an industrial temperature range?
Over a -40 °C to +85 °C industrial temperature span — a 125 °C swing — the ±200 ppm/°C coefficient produces a maximum resistance change of ±2.5% on top of the initial ±5% tolerance. For precision voltage dividers requiring better than ±1% stability, a lower TCR resistor such as a 0.1% film type would be preferred, but for general biasing the RK73B2ATTD334J performs reliably.
Is the RK73B2ATTD334J in 0805 a suitable replacement for a through-hole 330 kΩ resistor in a board redesign?
Yes — the 0805 (2 mm × 1.25 mm) SMT package replaces through-hole 330 kΩ resistors while reducing board area by roughly 80% and enabling automated pick-and-place assembly. The RoHS-compliant, lead-free termination meets the same environmental standards as modern through-hole equivalents, making it a straightforward swap during a surface-mount redesign of legacy consumer or industrial PCBs.
