• Manufacturer Part Number: HDSP-4820
• Description: (HDSP-48xx) 10-Element Bar Graph Array
• Manufacturer: Hewlett-Packard

Absolute Maximum Ratings
Notes:
1. See Figure 1 to establish pulsed operating conditions. Maximum pulse width is 1.5 ms.
2. See Figure 2 to establish pulsed operating conditions. Maximum pulse width is 1.5 ms.
3. See Figure 8 to establish pulsed operating conditions. Maximum pulse width is 2 ms.
4. Derate maximum DC current for Red above T
5. Derate maximum DC current for HER above T
6. Clean only in water, isopropanol, ethanol, Freon TF or TE (or equivalent), or Genesolve DI-15 (or equivalent).
7. Absolute maximum ratings for HER, Yellow, and Green elements of the multicolor arrays are identical to the HDSP-4830/4840/
8. Maximum tolerable component side temperature is 134 C during solder process.
