The part number **47DM-1026-R** typically refers to a specialized **Display Module**, often associated with digital panel meters or specific industrial controller displays. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. Technical Specifications This component is generally a 7-segment LED display module used for numerical readouts. | Parameter | Specification | |:---|:---| | **Part Number** | 47DM-1026-R | | **Type** | LED Display (7-Segment) | | **Color** | Red (indicated by the "-R" suffix) | | **Digit Height** | Approximately 0.40 inches to 0.50 inches | | **Connection** | Common Anode or Common Cathode (configuration specific) | | **Mounting Type** | Through-Hole (THT) | --- ### 2. Electronic Characteristics To integrate this part into a circuit, the following electronic properties must be considered: #### Voltage and Current * **Forward Voltage ($V_f$):** Typically **1.8V to 2.2V** per segment. * **Forward Current ($I_f$):** Usually rated at **10mA to 20mA** per segment for standard brightness. * **Peak Current:** Can handle higher pulses (up to 50mA) if PWM (Pulse Width Modulation) is used for multiplexing. #### Pins and Wiring The module consists of pins corresponding to: * **Segments A-G:** The individual bars that form numbers. * **DP:** The Decimal Point. * **Common Pin:** Depending on the internal wiring, this is either the Ground (Cathode) or VCC (Anode). --- ### 3. Applications The 47DM-1026-R is commonly found in the following devices: 1. **Digital Voltmeters:** Providing the visual interface for voltage readings. 2. **Industrial Timers:** Displaying countdowns or process times. 3. **Home Appliances:** Used in microwave or oven clocks where high visibility is required. --- ### 4. Implementation Example (C++ / Arduino) If you are connecting this to a microcontroller, you would use a current-limiting resistor (approx. 220Ω) for each segment. ```cpp // Example: Driving a segment high int segmentA = 2; void setup() { pinMode(segmentA, OUTPUT); } void loop() { digitalWrite(segmentA, HIGH); // Turns on Segment A delay(1000); digitalWrite(segmentA, LOW); delay(1000); } ```
