MCR10EZHMFX7151E Descripción general
A thick film chip resistor is a passive component in which a metal-oxide resistive paste is screen-printed onto a ceramic alumina substrate, then fired at high temperature to form the resistive element. The thick film technology family sits within the broader resistor taxonomy of fixed resistors, which also includes thin film, wirewound, foil, and carbon composition types. Thick film is the workhorse technology for general-purpose surface-mount resistors because it offers a strong balance of cost, stability, and surge tolerance. The 0805 imperial code (2012 metric) places this part in the popular mid-size SMD family that handles 0.125 W comfortably with standard reflow profiles.
Key features of the MCR10EZHMFX7151E include 7.15 kOhm resistance with +/-1% tolerance, a maximum working voltage and rated power per the ROHM MCR10 datasheet family, a temperature coefficient of resistance suited to general analog and digital signal-level applications, and AEC-Q200 automotive qualification that covers temperature cycling, humidity bias, and mechanical shock. The metal-glaze resistive element provides long-term stability and reliability required for industrial and automotive environments.
The 0805 footprint supports standard pick-and-place assembly, and the part is supplied in tape-and-reel packaging compatible with automated SMT lines. Its 1% tolerance and 0.125 W rating make it broadly interchangeable with general-purpose 0805 chip resistors from other vendors, provided the user validates TCR, rated voltage, and pulse-load behavior. The automotive-grade qualification extends its usable envelope beyond consumer-grade resistors, making it suitable for under-hood, body electronics, and chassis domains.
Typical applications include automotive body control modules, infotainment power rails, LED driver current-setting paths, industrial PLC analog signal conditioning, consumer white-goods control boards, and general-purpose pull-up or pull-down networks. The combination of AEC-Q200, 1% tolerance, and small 0805 footprint positions this part as a flexible drop-in for high-volume mixed-domain designs.
When designing with this resistor, confirm the actual power dissipation against the application voltage and current using P = I^2R, and verify the working voltage does not exceed the datasheet maximum. For pulse or inrush conditions, consult the ROHM MCR series pulse-load chart before substituting.

Aplicaciones típicas
MCR10EZHMFX7151E es adecuado para 6 aplicacións: Automotive Body Control Module, LED Indicator Current Limiting, Industrial PLC Analog Signal Conditioning, Consumer White Goods Control Board, Power Supply Feedback Network, IoT Sensor Node Pull-Up Resistor.
Automotive Body Control Module
The MCR10EZHMFX7151E is well suited for automotive body control modules where AEC-Q200 qualification, ±1% tolerance, and 0.125 W power rating cover the standard signal-level resistance needs. At 7.15 kΩ it commonly serves as an LED current-limit resistor, pull-up for digital inputs, or input-conditioning resistor for switch debouncing networks. Its 0805 footprint matches the dominant automotive PCB land pattern standard, and the thick film metal-glaze element tolerates the temperature cycling and humidity bias tests defined by AEC-Q200. Designers benefit from second-source flexibility because four major resistor manufacturers offer functionally identical drop-in alternatives on the same footprint.
Recomendado
LED Indicator Current Limiting
In LED indicator circuits on automotive dashboards, infotainment panels, and industrial HMIs, the MCR10EZHMFX7151E provides a precise current-setting element. At 7.15 kΩ with a 5 V rail and a 2 V LED forward voltage, the current is approximately 0.42 mA, producing a soft indicator brightness suitable for status LEDs. The 0.125 W rating dissipates only about 1 mW, leaving enormous thermal margin. The ±1% tolerance ensures consistent brightness across production batches, important for matching multi-LED arrays on a single display module.
Recomendado
Industrial PLC Analog Signal Conditioning
Industrial PLC analog input modules use 7.15 kΩ resistors as input dividers, filter components, and scaling elements for 0-10 V or 4-20 mA signal chains. The MCR10EZHMFX7151E's ±1% tolerance provides adequate accuracy for 8 to 12-bit ADC front-ends, while its AEC-Q200 rating exceeds the standard required for industrial environments. Its thick film construction tolerates voltage transients on field wiring better than thin film, and the 0805 footprint supports standard wave-and-reflow assembly compatible with mixed-technology PLC boards.
Recomendado
Consumer White Goods Control Board
Washing machines, dishwashers, refrigerators, and ovens use 0805 thick film resistors like the MCR10EZHMFX7151E for keypad pull-ups, relay driver bases, and microcontroller reset networks. The 7.15 kΩ value is common for pull-ups on I²C or switch-matrix lines. While consumer-grade parts would suffice for indoor appliances, AEC-Q200 automotive-grade resistors like this one are increasingly specified for white goods to gain extra margin against humidity and temperature stress in laundry and kitchen environments.
Recomendado
Power Supply Feedback Network
Isolated and non-isolated DC-DC converters frequently use 7.15 kΩ thick film resistors in feedback divider networks setting output voltage. The MCR10EZHMFX7151E's ±1% tolerance is sufficient for converters with ±2-3% output accuracy targets, while the 0.125 W rating handles typical feedback currents below 1 mA without thermal stress. The thick film technology provides better surge tolerance than thin film in feedback loops that may see voltage transients during converter startup or load dump events.
Recomendado
IoT Sensor Node Pull-Up Resistor
IoT sensor nodes for smart home, building automation, and asset tracking use 0805 thick film resistors as I²C pull-ups, sensor-bias resistors, and mode-selection pull-downs. The MCR10EZHMFX7151E at 7.15 kΩ is a strong candidate for sensor-bias networks on temperature, humidity, and motion sensors where moderate pull strength is needed. Its small 0805 footprint preserves board area for the radio and antenna, while its RoHS compliance and lead-free reflow compatibility fit modern SMT production.

- Drop-in compatible with all major 0805 thick film automotive resistor lines (frente a RC0805FR-077K15L)

Notas de diseño
Power dissipation for the MCR10EZHMFX7151E must be calculated using P = I²R or P = V²/R and compared against the 0.125 W rating at 70°C ambient. Above 70°C, derate linearly to zero at 155°C per the AEC-Q200 envelope. For a 7.15 kΩ resistor at 5 V, dissipation is about 3.5 mW; at 30 V it rises to 126 mW, which already exceeds the rating in worst-case conditions. Always check steady-state dissipation at maximum input voltage including tolerances, and confirm the PCB copper area provides adequate heat spreading.
Use the IPC-7351 standard 0805 land pattern: pads approximately 1.20 mm x 0.90 mm with 0.50 mm spacing between pad edges, on a non-solder-mask-defined pad. Solder paste stencil aperture should be slightly smaller than the pad (typically 90% coverage) to prevent solder beads and tombstoning. ROHM recommends Ni/Sn-plated terminations compatible with lead-free SAC305 reflow profiles peaking at 245-260°C. For double-sided assemblies, mount heavy components on the bottom side to minimize stress on the top-side 0805 chip resistor.
Do not confuse the EIA-96 resistance code '7151' (7.15 kΩ) with the older 3-digit '715' code or other 4-digit codes; misreading yields 10x or 100x resistance errors. Also, confirm whether your application requires the 'EZH' automotive grade or the cheaper 'EZP' industrial-grade variant - they share the same footprint but differ on qualification level. When substituting across brands, verify that the alternative's working voltage and TCR meet the precision needs of analog signal paths, because cross-brand thick film parts can vary ±50 to ±200 ppm/°C.
