Panasonic EXB-28V510JX 51 ohm 0804 SMD Resistor Arrays 40 PCS

Genuine Panasonic EXB-28V510JX surface-mount resistor arrays, supplied as one lot containing 40 pieces from original DigiKey distributor-labeled stock.

Each miniature resistor array contains four electrically isolated 51 ohm resistors with ±5% resistance tolerance, providing a total of 160 individual resistor elements across the 40-piece lot.

Part of Panasonic's EXB series, these resistor networks are designed for compact electronic assemblies requiring multiple fixed resistors within a single surface-mount component.

Each resistor element features a power rating of 0.0625W (1/16W), a temperature coefficient of ±200 ppm/°C, and an operating temperature range of -55°C to +125°C.

The 0804 surface-mount package features eight terminals arranged along its longer sides, with convex terminal construction. Nominal package dimensions are approximately 2.0 × 1.0 mm, with a maximum component height of 0.45 mm.

These resistor arrays are AEC-Q200 automotive-qualified and suitable for compatible electronic assemblies requiring compact, isolated resistor networks.

Typical applications include digital signal lines, pull-up and pull-down networks, electronic control circuits, signal conditioning, industrial instrumentation, communications equipment, automotive electronics, and component-level PCB repair.

The original DigiKey distributor label is dated August 19, 2021, identifies Japan as the country of origin, and confirms RoHS3 compliance.

HISTORICAL BACKGROUND:

Panasonic traces its origins to 1918, when Konosuke Matsushita established an electrical manufacturing business in Osaka, Japan.

Over subsequent decades, Panasonic developed into a major international manufacturer of electronic equipment and components, including resistors, capacitors, batteries, and other passive electronic technologies.

As electronic circuit boards became smaller and more densely populated, manufacturers developed resistor-network packages that combined multiple resistive elements within a single component.

Resistor arrays reduced the number of individual components requiring placement during automated circuit-board assembly and helped conserve valuable PCB space.

Isolated resistor networks contain multiple electrically independent resistors within one package, allowing circuit designers to use several resistance elements without requiring a shared electrical connection.

These components became useful in digital electronics, industrial controls, automotive circuits, communications equipment, and other systems requiring repeated resistor values.

Panasonic's EXB family includes miniature surface-mount resistor networks designed for compact electronic applications.

The EXB-28V510JX contains four electrically isolated 51 ohm resistors with ±5% tolerance in an eight-terminal 0804 package.

Its AEC-Q200 qualification supports use in appropriately designed automotive electronic systems.

The original DigiKey distributor packaging is dated August 19, 2021, documenting the stock history of these components.

The packaging identifies Japan as the country of origin for this particular stock.
