Detailed Description

0 ohm jumper resistor, 0402 package (1005 metric), thick film technology

Rated power 0.063 W (1/16 W)

Operating temperature range -55°C to +155°C

Two-terminal surface-mount link used to bridge nets or set options in circuits

Very low profile for dense PCB layouts: about 1.00 mm x 0.50 mm x 0.40 mm (L x W x H)

Key Features

Value 0 ohm jumper for direct shorting and configuration links

Package 0402 for ultra-compact designs

Power rating 1/16 W for general-purpose use

Thick film on ceramic for stable, cost-effective performance

Wide operating temperature range -55°C to +155°C

Tolerance category Jumper (no resistance tolerance applies)

Two terminations, standard 0402 land pattern

RoHS and lead-free plating typical for the Walsin WR series (check datasheet to confirm lot specifics)

Moisture Sensitivity Level typically MSL 1 for passive thick-film resistors

Key Advantages

Simple, reliable way to route or reconfigure circuits without changing PCB copper

Saves space and cost versus jumpers or headers

Low profile 0.4 mm height fits under shields and in tight enclosures

Compatible with high-speed pick-and-place and reflow

Broad temperature range supports consumer, industrial, and many embedded uses

Standard footprint makes second-sourcing straightforward

Packaging

Form: Surface-mount chip resistor, size code 0402 (1005 metric)

Material: Thick-film resistive element on alumina ceramic substrate; Ni barrier with Sn finish on terminations (lead-free)

Carrier and reel: Typically paper tape on reel per EIA-481, 8 mm width; common reel options are 7 inch or 13 inch with high piece counts (confirm exact reel and piece count in datasheet or on our product page)

Size and dimensions: 0.039 in x 0.020 in x 0.016 in max (1.00 mm x 0.50 mm x 0.40 mm max)

Pin configuration: 2 terminals, standard 0402 pad layout

Thermal characteristics: -55°C to +155°C operation; power derates above 70°C per typical resistor derating curves (see datasheet for exact curve)

Electrical properties: 0 ohm link, rated 0.063 W; current capability is application and temperature dependent and limited by power and pad-to-ambient conditions (consult datasheet and perform thermal evaluation for your board)
