What are the key features of MCPWR12FTEA6802?
- 1.5 W power rating in compact 2512 SMD package eliminates heatsinking and reduces PCB footprint by 60% vs. through-hole equivalents
- 68 kΩ at ±1% tolerance enables precise divider networks and pull-up resistor applications without laser trimming
- Lead-free JESD-609 e3 compliance satisfies automotive and industrial RoHS requirements globally
What is MCPWR12FTEA6802 used for?
The MCPWR12FTEA6802 is widely deployed in high-voltage power supply designs as an input voltage divider feedback resistor in AC-DC converters (100-400 V utility rail), industrial motor speed control circuits using 24-48 V logic rails, and precision data acquisition pre-scaling networks. Its 68 kΩ value paired with 1 µF capacitors creates 2.3 Hz filter poles ideal for DC voltage monitoring in 3-phase industrial drives. The 1.5 W rating enables series connection with high-impedance transducers (photodiode arrays, bridge sensors) in isolated measurement chains.

Frequently Asked Questions
What is the maximum power dissipation of the MCPWR12FTEA6802 in a 2512 package, and how does it compare to 1206 alternatives for power supply feedback networks?
The MCPWR12FTEA6802 is rated for 1.5 W continuous dissipation in its 2512 package (6.35 × 3.1 mm, approximately 19.7 mm² footprint). Maximum safe current through 68 kΩ calculates to I = √(1.5 / 68000) ≈ 4.7 mA RMS. The 2512 package offers 4x the power capacity compared to 1206 (0.25 W typical), enabling higher bias currents in precision analog circuits while maintaining <100°C junction temperature rise. For AC-DC power supply designs operating 24/7, the 1.5 W rating eliminates thermal stress at rated loading, extending MTBF to 50+ years vs. 10-15 years for 1206-packaged alternatives operating at power limit.
How does the 68 kΩ resistance value optimize AC-DC converter feedback divider design when used with typical regulation error amplifiers?
In a 300 V AC input rectified to 424 V DC, a 68 kΩ feedback resistor pair (68 kΩ + 2.2 kΩ divider) produces approximately 13.7 V output after scaling, ideal for ±5 V regulated supply regulation loops. The 68 kΩ upper arm current at 424 V is 6.2 mA, dissipating 0.42 W — well within the 1.5 W rating even with series filtering. The high impedance (68 kΩ) minimizes loading on the error amplifier input, reducing bias current effects (typically <1 µA modern opamps) to below 1 mV offset. Compared to lower-value dividers (10 kΩ), the 68 kΩ choice reduces power consumption from 30 W to 2.7 W in idle standby mode.
Should you choose the MCPWR12FTEA6802 or a lower-tolerance part for automotive 48 V bus monitoring in electric vehicle battery management systems?
The MCPWR12FTEA6802's ±1% tolerance is essential for 48 V BMS applications where voltage accuracy directly impacts charge-balancing algorithms and cell-level overvoltage protection thresholds. A ±1% resistor divider produces 3.3 V reference from 48 V input with ±33 mV error (±1%), enabling 12-bit ADC-based monitoring with 12 mV per LSB quantization. If using ±5% resistors, the 48 V divider drifts by ±2.4 V — exceeding ±3 mV cell-balancing hysteresis and causing false over-voltage alarms. Choose MCPWR12FTEA6802 when BMS safety architecture depends on voltage measurement accuracy; use ±5% resistors only in non-critical indicator circuits.
