    Special Price $8.98 Regular Price $16.50 As low as $7.98

    General Electric - SSL-140 - LED Displays, Solid State Lamp (SSL) 

    One of General Electric's most well-known displays, the SSL-140 is an early seven-segment LED in a tiny surface mount package. The SSL-140 is a single die device, in that all of the segments are constructed on the same lump of silicon. The display's decimal point is a separate small cubical die located in the right side of the display area. The SSL-140's dies are bonded to a ceramic wafer with gold leads, with an enclosing plastic cover to protect the fragile dies and bond wires.

    Red 0.16" 7-Segment with Decimal Point

    Common Cathod

    20mA Max.

    One of the Very First LED displays - built in Cleveland by General Electric at the original Nela Lamp Plant. Nela Park was the first industrial park in the world being home to most of the lighting breakthroughs of the last century. 

    10 Gold Plated Leads

    Standard 10 pin display. Long leads also serve as a heat sink to prevent damage to the plastic enclosure. 

    The earliest LED’s, light emitting diodes, were produced in the early 1960’s. General Electric was one of the first companies to offer a visible light emitting diode in 1967. SSL LED Prices back than where between $4 and $32 apiece.

  22. ISEDEN - DG10A / DG10C - Gas-discharge tube with a 7 segment display.
    ISEDEN - DG10A / DG10C - Gas-discharge tube with a 7 segment display.
    Special Price $4.98 Regular Price $6.00

    ISEDEN - DG10A / DG10C Gas-discharge tube with a 7 segment display.

    A gas-filled tube, also commonly known as a discharge tube or formerly as a Plücker tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. Gas-filled tubes exploit phenomena related to electric discharge in gases and operate by ionizing the gas with an applied voltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge. A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps, sodium-vapor lamps, and neon lights. Specialized gas-filled tubes such as krytrons, thyratrons, and ignitrons are used as switching devices in electric devices.

    This flying lead display tube has color coded plastic sleeves on its leads, which makes it easier to wire than most VFD tubes. The tube is smaller than most, and digit height is 9mm.

    Dimensions: 10mm D x 35mm tall with (12) 20mm wire leads.

    Note: Iseden / Itron.
