DLP2010: About data sheets 6.2 Storage Conditions and 6.4 Recommended Operating Conditions

Part Number: DLP2010

Hello,

I have three questions about the DLP 2010 data sheet.

1. About  6.2 Storage Conditions,

    What do meanings of Long-term and Short-term of Dew Point Temperature mean?

 Specifically, are there numerals of Long-term and Short-term?

2. About 6.4 Recommended Operating Conditions, 

    Is there definition of long-term and short-term operation of Array Temperature?

3. I have a question about 14th annotation.

 What is the life span of DMD when used from 0 ° C to 75 ° C?

I'm looking forward to getting your reply.

Best Regards,

Leo

  • Hello Leonardo,

    Let me try to address each of these questions individually.

    1. "Long-term" and "Short-term" are defined on page 6 in the datasheet as:

    Long-term: The usable life of the device
    Short-term: Less than 60 cumulative days over the usable life of the device

    2. "Long-term" and "Short-term" are defined on page 8 in the datasheet as:

    Long-term: The usable life of the device
    Short-term: Short-term is defined as cumulative time over the usable life of the device and is less than500 hours for temperatures between long-term maximum and 75°C, less than500 hours for temperatures between 0°C and -10°C, and less than 25 hours for temperatures between -10°C and -20°C.

    3. Unfortunately, we do not provide a formal specification for DMD lifespan for this device.

    I hope this helps.

  • Hello Philippe

    Thank you for your support always.

    Why short-term is for more than the dew point of the long-term?

    Although it was understood that condensation occurs in the DMD when the dew point temperature is exceeded,
    I do not know if there is a difference in temperature between long term and short term.

    For example, if I want to set a lifetime of 250 hours, how many ambient temperatures do I have?
    Also, is there a calculation method of life time?

    Best Regards,

  • Leonardo,

    The dew point measurement is higher for short term use generally because we have specified that the device is capable of withstanding harsher conditions for a limited duration while still maintaining operation.

    You may experience better device lifetime by operating under more conservative conditions. While there is not a formal method to calculate life time, we recommend designing around the given dew point specifications for applications typical to this DMD.

    I hope this helps.
