202 SERIES

Product catalog summary

Features and Benefits:

The 202 Series LED bulbs are designed as direct replacements for standard bulb fittings, featuring a T1 Midget Flange SX3s Base and a water-clear lens for clear 'off' state visibility.
They offer a range of LED color and voltage options, with a flat-topped design for even illumination.
These LEDs are manufactured with an internal resistor, ensuring outstanding reliability and eliminating the need for color filters.

Technical Specifications:

Available in various colors including Red, Yellow, Green, Blue, Warm White, and Cool White, with typical operating voltages ranging from 5-6V to 48V.
Operating temperature ranges from -30°C to +85°C, with storage temperatures from -40°C to +85°C.
LEDs are supplied in anti-static packaging to prevent electrostatic discharge damage.

Design Considerations:

Single-chip LEDs are used, with flat-topped designs for even illumination, although non-flat topped versions are available.
LEDs are designed for improved reliability, suitable for both new-build and retro-fit applications.
Evaluation of LED types is recommended to ensure compatibility with existing systems and optimal viewing characteristics.

Electro-Static Discharge (ESD) Precautions:

ESD can cause irreversible damage to LEDs; therefore, precautions must be taken during manufacture and assembly.
MARL follows BSI guidelines for ESD protection and recommends users do the same.

Voltage, Current, and Temperature Considerations:

The forward voltage/current of an LED depends on the ambient temperature, requiring careful operation within specified ranges.
MARL should be contacted for operations outside the specified temperature range, as they accept no liability for such cases.

Technical Data and Graphs:

Technical drawings and de-rating graphs are provided to assist in understanding the performance characteristics of the LEDs under different conditions.
