EXB-U2H102JV Panasonic Electric Works

The Panasonic EXB-U2H102JV is a high-reliability, anti-sulfurated chip resistor array designed for space-constrained and harsh environment applications. Part of the EXB-U series, this SMD/SMT component integrates eight isolated 1 kOhm resistors with a 5% tolerance into a compact 1506 (3.8mm x 1.6mm) package with 16 pins. It offers a total package power rating of 250 mW (63 mW per element) and a voltage rating of 25 V. With a temperature coefficient of 200 PPM/°C and an operating range of -55°C to +125°C, this AEC-Q200 qualified array ensures stable performance in automotive, industrial, and consumer electronics where board space is at a premium and resistance to sulfur contamination is critical.

Features

• High Integration: Combines 8 isolated resistors in a single 1506 package, significantly reducing PCB footprint and component count compared to discrete resistors.
• Anti-Sulfuration Protection: Specifically designed as an anti-sulfurated chip resistor array, ensuring long-term reliability in environments with high sulfur gas concentrations.
• AEC-Q200 Qualified: Meets stringent automotive-grade reliability standards, making it suitable for demanding applications requiring high thermal and mechanical stress tolerance.
• Wide Operating Temperature Range: Rated for operation from -55°C to +125°C, ensuring stable performance across extreme environmental conditions.

Pin Configuration and Functions

• No pin definition: This is a passive resistor network. Pin 1 is typically identified by a polarity mark on the package, but the device is non-polarized. The 16 pins correspond to the terminals of 8 isolated resistors (e.g., pins 1 & 16 for R1, pins 2 & 15 for R2, etc.).

Typical Applications

• Automotive ECU Pull-up/Pull-down: Used for digital signal conditioning in engine control units and transmission modules.
• Industrial Sensor Interfaces: Provides stable voltage division and current limiting for temperature and pressure sensors.
• Consumer Electronics Power Management: Suitable for DC-DC converter feedback networks in compact devices like laptops and IoT modules.
• Telecommunications Line Termination: Functions as a bus termination array for RS-485 or CAN bus interfaces.

Equivalent / Alternative Parts

• EXB-U2H102J (Panasonic): Direct equivalent with identical specifications, package, and pinout.
• YC164-JR-071KL (Yageo): Alternative with same 1kΩ resistance, 5% tolerance, and 16-pin 1506 package, but may lack specific anti-sulfuration rating.

Design-in Tips

• Optimize Solder Profile: Follow JEDEC standard reflow profiles with a peak temperature of 260°C to ensure proper solder joint formation without damaging the anti-sulfuration coating.
• Verify Pin 1 Orientation: Although the device is non-polarized, confirm the orientation mark on the PCB layout to ensure consistent pick-and-place alignment and visual inspection.
• Derate Power at High Temperatures: For operation above 70°C, linearly derate the total package power (250 mW) to prevent thermal stress and maintain long-term reliability.
