Key Features
- 120 kΩ high-resistance value suitable for voltage dividers, bias networks, and high-impedance signal conditioning
- 0.5 W power dissipation in a 1210 (3.2 mm × 2.5 mm) SMD package offers greater thermal headroom than smaller 0805/1206 alternatives
- ±200 ppm/°C TCR delivers adequate thermal stability for general-purpose resistor applications across industrial temperature ranges
- RoHS and REACH compliant (JESD-609 e3, Pb-free), meeting global environmental regulations
- Panasonic ERJT14 series provides long-term supply chain reliability with a 12-year product lifecycle
Applications
The ERJT14J124U is used in voltage divider networks, op-amp feedback resistors, and high-impedance bias circuits in industrial controls, medical instrumentation, and consumer electronics. Its 120 kΩ value limits quiescent current to a few microamperes at typical supply voltages, making it energy-efficient in battery-powered applications. The 1210 SMT footprint supports automated assembly and provides better power handling than smaller packages where reliability at elevated board temperatures is a concern.

Frequently Asked Questions
What quiescent current does a 120 kΩ ERJT14J124U draw when used as a pull-up resistor on a 5 V logic rail?
On a 5 V rail, the 120 kΩ ERJT14J124U draws approximately 41.7 µA (I = V/R = 5 V / 120 kΩ), consuming only about 208 µW — well within its 0.5 W rating — making it an energy-efficient pull-up choice for low-power microcontroller I/O lines in battery-operated devices.
How does the 0.5 W 1210 package of ERJT14J124U improve thermal reliability compared to a 1206 version of the same 120 kΩ value?
The 1210 package (3.2 mm × 2.5 mm) has 56% more pad area than a 1206, allowing better heat spreading to PCB copper pours; at 0.5 W versus the 1206's 0.33 W rating, the ERJT14J124U provides greater safety margin in circuits where 120 kΩ resistors experience intermittent high-voltage transients up to 245 V peak.
Which feedback-resistor applications benefit most from pairing two ERJT14J124U resistors in a divider?
In op-amp non-inverting amplifiers or ADC input attenuators, two 120 kΩ resistors forming a 1:1 divider produce a mid-rail reference at half the supply voltage with only 83 µA total quiescent current at 10 V; the ±5% matched tolerance keeps the divider ratio within ±7% worst-case, acceptable for general-purpose level shifting but not for precision references requiring better than ±1%.
