What are the key features of ERJ8ENF39R0V?
- 39 ohm thick film resistor with 1% tolerance for precision signal conditioning and voltage divider circuits
- 0.25 W power rating in compact 1206 (3.2 mm x 1.6 mm) SMD package suitable for automated reflow assembly
- RoHS compliant and REACH conformant with e3 JESD-609 rating for lead-free manufacturing environments
What is ERJ8ENF39R0V used for?
The ERJ8ENF39R0V is used in precision analog front-end circuits, current-sensing networks, and filter designs where a stable 39 ohm, 1% tolerance thick film resistor is required at power dissipations up to 0.25W. Its 1206 package is well suited to industrial control boards and power supply feedback networks where hand soldering or pick-and-place assembly is standard. The precision tolerance also makes it suitable for voltage reference dividers and impedance matching in communications hardware.

Frequently Asked Questions
What is the resistance value and tolerance of Panasonic ERJ8ENF39R0V, and how does that precision compare to general-purpose alternatives?
The ERJ8ENF39R0V has a resistance of 39 ohms with 1% tolerance, placing it in the precision category versus the 5% tolerance of standard thick film resistors. In a voltage divider operating at 3.3 V, a 1% tolerance on a 39 ohm resistor limits the worst-case output error to ±33 mV, whereas a 5% resistor would allow up to ±165 mV error—critical in analog sensor conditioning or ADC reference circuits.
How much power can ERJ8ENF39R0V safely dissipate, and what limits its use in high-current sensing applications?
The ERJ8ENF39R0V is rated for 0.25 W continuous power dissipation. At 39 ohms, this means the maximum current through the resistor is approximately 80 mA (I = sqrt(P/R) = sqrt(0.25/39) ≈ 0.080 A). For current sensing above 80 mA, a higher power rating such as 0.5 W or 1 W in the same 39 ohm value would be required to avoid thermal stress.
Which physical dimensions define the 1206 package of ERJ8ENF39R0V, and how does it affect PCB layout?
The 1206 package has a body length of 3.2 mm and body height of 0.6 mm, making it one of the larger standard SMD resistor packages and easier to hand-solder than 0603 or 0402 alternatives. The larger pad area also improves thermal dissipation, allowing the 0.25 W rating to be fully utilized. PCB designers should allow standard 1206 land patterns with 1.6 mm pad width to ensure reliable solder joint formation during reflow.
