LED lamps take shunt resistors onboard
A series of lamp-based LEDs feature built-in shunt resistors to reduce unwanted illumination caused by leakage current.
DDP has developed a series of lamp-based LEDs that feature built-in shunt resistors to reduce unwanted illumination caused by leakage current Well-suited for industrial environments, power generation, transmission and distribution applications, the LS Series is designed to be a direct replacement for incandescent bulbs

DDP has developed an LED lamp assembly for railway indication lighting applications.
LS Series lamps offer upwards of 100,000-hour life, shock and vibration resistance, low heat, and low power consumption.
"Burned-out incandescent bulbs can create safety concerns, require costly maintenance and repair, and result in significant downtime", said Tony Toniolo, DDP President.
"Our LED lamps provide many years of high reliability, maintenance-free operation".
"DDP engineers designed-in shunt resistors to our products specifically for the unique environments they operate in".
According to Toniolo, there are several potential sources of leakage current in a typical circuit, including transient voltage from a relay or discharge from a capacitor.
Certain programmable logic controllers (PLCs) may supply up to 5mA of leakage current in the "off" state.
Because LEDs are so efficient, a current as low as 0.25mA can cause an LED to illuminate.
The LS Series lamps incorporate parallel shunt resistors to bleed off residual current in the circuit that could otherwise cause a false "on" indication.
DDP incandescent light replacement solutions are available in either standard or custom assemblies.
Pricing for a standard 9mm MB LED lamp starts at $11.00.
Samples are available from DDP with a lead-time of stock to one week.
